Sunday looks set to be cooler than most recent days, with The Met Office currently predicting highs of 20C. The forecaster said there is a small chance of disruption if the storms are severe – including spray and sudden flooding, damage to buildings through flooding, cancellations on trains and other public transport networks and power cuts.

Despite this, The Met Office believes some areas will be hit harder than others. They said: ‘Whilst many areas will see at least some rain, most will see only relatively small amounts.

‘However, some places could see 30mm in an hour and 60mm in six hours, with the potential for frequent lightning, strong winds and hail. Where this occurs there is likely to be some disruption.

‘While there is a high likelihood that thunderstorms will develop over England and Wales, there remains a large amount of uncertainty in exactly where these develop. This uncertainty is likely to remain even up to short lead times.’

Saturday is expected to be dry and mostly cloudy, with temperatures peaking at 21C, according to the Met Office.
